The title makes reference to a passage from the lyrics in which the singer, having been left by his girlfriend, gets rid of woes by eating "kilos of jam", exactly the same one that the girl had hid from him.

[1] An alternate version of the track, "Marmellata #24", was issued as a B-side on the subsequent single "Maggese".

The single of the song was released in store on 16 May 2005, almost a month ahead of the full album Maggese.

Filmed in 35 mm by Gaetano Morbioli for Run Multimedia, the video of "Marmellata #25" sees the singer awake one morning to find that all the objects of his apartment had come to life.

When Cremonini leaves the apartment and thinks himself to be free, he finds himself face to face with a giant spider (formed by the objects of his home) that follow him on the streets of Bologna, until arriving at the Giardini Margherita, where Cremonini bangs his head against a branch and passes out.
